Runoff trends analysis and future projections of hydrological patterns in small forested catchments
climate change flow pattern headwater catchments hydrological modelling
2015/3/10
The aims of the present study were (i) to evaluate trends in runoff from small forested catchments of the GEOMON (GEOchemical MONitoring) network during the period 1994–2011, and (ii) to estimate the ...
Impact of landuse on runoff in mountain catchments of different scales
hydrological regime landuse change
2015/2/4
The paper presents two approaches to the analysis of the impacts of landuse changes on hydrological regime in mountain catchments of northern Slovakia. An intersite comparison of measured data along t...
Annual changes in the chemical composition of stream water in small catchments with different land-use (Carpathian Foothills, Poland)
river water chemistry water pollution nutrient compounds flow tendency
2015/2/4
The aim of the study was to identify the factors that influence annual changes in the chemical composition of stream waters. The research area was located in the marginal zone of the Carpathian Foothi...
The Wageningen Lowland Runoff Simulator (WALRUS): a lumped rainfall–runoff model for catchments with shallow groundwater
The Wageningen Lowland Runoff Simulator rainfall–runoff
2014/12/19
We present the Wageningen Lowland Runoff Simulator (WALRUS), a novel rainfall–runoff model to fill the
gap between complex, spatially distributed models which
are often used in lowland catchme...
Streamflow trends in Europe: evidence from a dataset of near-natural catchments
Streamflow trends Europe dataset
2010/12/22
Streamflow observations from near-natural catchments are of paramount importance for detection and attribution studies, evaluation of large-scale model simulations, and assessment of water management,...
Performance and reliability of multimodel hydrological ensemble simulations based on seventeen lumped models and a thousand catchments
multimodel hydrological ensemble simulations seventeen lumped models
2010/12/22
This work investigates the added value of ensembles constructed from seventeen lumped hydrological models against their simple average counterparts. It is thus hypothesized that there is more informat...
The role of climatic and terrain attributes in estimating baseflow recession in tropical catchments
climatic terrain attributes estimating baseflow recession tropical catchments
2010/12/22
The understanding of low flows in rivers is paramount more than ever as demand for water increases on a global scale. At the same time, limited streamflow data to investigate this phenomenon, particul...
Application of WaSiM-ETH model to Northern German lowland catchments: model performance in relation to catchment characteristics and sensitivity to land use change
WaSiM-ETH model Northern German lowland catchments model performance in relation to catchment characteristics sensitivity land use change
2010/9/10
The hydrological catchment model WaSiM-ETH (Water Balance Simulation Model) is a spatially distributed, process- and grid-based hydrological catchment model which was primarily developed to simulate t...
Characterising the origin, nature and fate of sediment exported from catchments perturbed by active tectonics
Characterising the origin, nature fate of sediment exported from catchments perturbed active tectonics
2014/5/20
Changes to the tectonic boundary conditions governing erosional dynamics in upland catchments have a significant effect on the nature and magnitude of sediment supply to neighbouring basins. While the...
SEPAL – a simple GIS-based tool to estimate sediment pathways in lowland catchments
SEPAL GIS
2010/2/3
Even though soil loss in the lowlands imposes not as much a restriction on land use and agricultural productivity as in erosion affected mountainous areas, the input of fine sediment into the rivers a...
Climate and terrain factors explaining streamflow response and recession in Australian catchments
Climate and terrain factors streamflow response recession Australian catchments
2010/2/1
Daily streamflow data were analysed to assess which climate and terrain factors best explain streamflow response in 183 Australian catchments. Assessed descriptors of catchment response included the p...
